Have been using a blue spark condenser mic for the past two years or so. had no problems till recently. when i boost the gain to usable levels i hear very bad wind noise that peaks the mic. Here's an audio sample. http://www.mediafire.com/?v65kvtu7p8opjbj
The noise clip is only during the first 25 secs. Normal expected sounds are the clock ticking in the background and the hum from my aircond. The issue is the intermittent buffeting noise (as if there was a gust of wind), any ideas?
